IMPROVEMENT IN SPINDLES.

Specification forming part of LcttersPatcnt No. 220,357, dated October 7, 1879 application filed July 19, 1879.

To all whom it may concern:

Be it known that we, J osnrn DUFFY and HENRY WHORWELL, ofPaterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Spindles and Bolsters; and we do hereby declare that the following is a full, clear, and exact description of the same.

Our invention relates to devices for spinning silk and other fibrous material; and its object is twofold-first, to provide a bolster which shall support the spindle firmly, and yet be adapted to permit the spindle and its attached whirl to be conveniently detached when required; second, to facilitate the lubrication of the spindle-bearin gs.

To these ends we adopt the construction hereinafter described, and shown in the accompanying drawings, in which Figure 1 is a side view, and Fig. 2 avertical section, of the spindle and bolster, the latter being attached to a rail.

The spindle Atravels in the bolster B, which is secured in the supporting-rail G by means of a clamp-screw, D. The tubular lower part, a, and the vertical arms b of the bolster constitute its body or integral portion, while the bridge-piece E, which forms the upper bearing of the spindle, is made detachable, being secured to and between said arms I) by means of screws 0?. Such adaptation of the bearing E for detachment enables the spindle A and its attached whirl F to be conveniently removed from the bolster when occasion requires, it being only necessary to first remove the screws d andthen slide the bearing E upward; yet

when the bearing E is in place, as shown in the drawings, the spindle is supported firmly, so that it runs with perfect steadiness.

An annular oil cavity or cup, f, is formed in the bearing E, concentric with the spindle. From said cup the oil descends along the spindle and enters an annular cup, i, formed in the upper side of the whirl F, which is provided with an annular flange to receive a corresponding flange of bearing E.

As a well-understood fact, the oil which descends from cup f into cup twill be forced back up the spindle, and thus continue to circulate until evaporated or used up.

An annular oil-chamber, l, is also formed in that part of the tubular portion a of the bolster which fits in the rail 0, and a countersink is formed at m, to facilitate the entrance of the lubricant into such cavity.

What we claim is- 1. The bolster having the tubular lower portion, a, and arms I) made in one piece, and the detachable bridge or upper spindle-bearin g, E, and the screws d, all combined as shown and described.

2. The combination of the upper spindlebearing, E, body B of the bolster, and the whirl F, said parts having, respectively, the annular oil cavities or cups f l t and countersink m, all as shown and described.
